![]() ![]() ![]() It is still unknown exactly how much the snail can actually see. Snails have eyes located on the tip of its top tentacles. They also have tactile receptors which mean they respond to light touch. This pair of tentacles is usually shorter than the upper pair.Īll of the tentacles are retractable which mean the snail can pull them back when he needs to or when he senses danger. The lower pair of tentacles have smelling capabilities. Two at the top of the head and two at the bottom. The tentaclesĪ land snail will usually have two pairs of tentacles. On the head you will see the mouth and 2 to 4 tentacles. The head of the snail is located on one end of its body. Snails can pick up on those trails to find other snails for mating purposes. You can usually see the mucus as it dries because it becomes a sort of a shiny trail. Video can’t be loaded because JavaScript is disabled: EXPERIMENT Snail on Razor! () That mucus has many amazing abilities that allows a snail to move completely vertically without falling and even crawl over a sharp blade without damaging its skin. The snail is using his muscular foot to create small wave motions of contractions and expansions in order to move around.ĭuring their glide, the snail will reduce the friction by creating mucus. The foot is basically the bottom part of the snail’s body. But they do have something that is called the foot. It is also critical in cases where the snail has a damaged shell. The consumption of calcium helps the snail to have a bigger and harder shell. Since the shell is made mostly from calcium, the snail requires a lot of calcium in its diet. They will seal the opening of the shell with some kind of mucus that will become hard and protect the delicate body temperature and humidity. Depending on the snail habitat, if it is too hot or too cold and dry, they will go inside the shell. Some species will use the shell as a protection from unsuitable weather conditions. Whenever it feels danger, the snail will retract itself into his shell. It is also the snail’s protection from predators. The main purpose of the shell is to protect the snail’s internal anatomy parts that will be explained later. They will add more and more whorls to fit the snail’s body. As he grows up and his body gets bigger, so does its shell. ![]() A baby snail will have a shell with only one whorl. Snails are born with a small transparent shell. But they all have a spiral design made of several whorls and consist mostly from calcium. They are different in size, color and shape. It is also the main difference between a snail and its close family relative, the slug.ĭifferent species have different shells. ![]() The external shell is one of the first things you notice about the snail. Their estimated age is about 500 million years. In total, this class includes 65,000 to 80,000 different species. Gastropods class includes all types of snails, meaning land snails, freshwater and saltwater. The complete classification of the snails in the classification hierarchy is: Eukaryote -> Animal -> Eumetazoa -> Bilateria -> Protostome -> Lophotrochozoa -> Mollusca -> gastropods. The snails are gastropods class while the bugs and insects belong to the Insecta class. On the Animal kingdom classification they belong to two different classes.
